Sensor Webs Unwire Ecology
jonbrewer writes "Pioneered by CENS, Sensor Networks are rapidly becoming a mainstream environmental monitoring tool. The NY Times has an article today with a quick tech overview and info on RiverNet, EarthScope, NEON, and Neptune. The Times reports 'scientists want to deploy millions of these kinds of devices over large tracts for long periods, opening new windows on nature.'"
Sensor Webs and Smart Dust and related tecnologies will prove valuable in ecological studies and environmental monitoring, but that's not the drive behind them.
In Vietnam the US military attempted to install networks of sensors - seismographs, detectors for urine and sweat, detectors for nitrogen compunds (explosives), movement detectors, proximity detectors - along known NLF supply lines and for perimeter defence. They were put in place by Special Forces teams and transmitted their data to overflying aircraft for targetting. Often they were woeful failures or could be spoofed by the NLF.
Here is the new generation, just ready for "assymetric warfare".
Having participtated in small scale ecology studies, I would guess that these senors will raise many more questions (which would be a good definition of the "new windows") than answers. Population ecology and the evolutionary biology that ties into it is a field with many more 'big' questions than most people realize.
In most of the primary literature I cover, for every possible cause of a behavior (such as migratory routes) that is eliminated, another 2 consistently appear (seriously). I think we will see some very interesting questions, rather than any definite answers (at least in the short term). I would definitely like to see this used with the arctic tern.
